Dust, also known as grit, quarry dust, quarry screening, and decomposed granite, is one of the most commonly used stone byproducts. It is a looser, darker version of sand that is processed through a crushing machine, which in turn produces crushed stone. The machine's screen traps the larger pieces of crushed stone, so only the smaller …
